The community continues with small, undocumented changes in Patch 9.2.5, released a week ago, and this time they noticed that the On the offensive meta-achievement, which requires participating in the Covenant attacks on the Maw events, has become easier to complete. Now, to receive it, it is enough to register 4 out of 9 of any achievements included in it.
Interestingly, this is not the first such change. The achievement originally required all 9 objectives to be completed during Patch 9.1 testing, then was reduced to 6, and now to 4. The developers apparently felt that it was too difficult for players in its previous form, so they decided to simplify it in order to they could complete the global meta-achievement Shadowlands - Back from the beyond added in update 9.2.5 with the title "Veilstrider" faster and easier.
